To all whom it may concern:

' Be it known that We, LEWIS C. Bnononnn and J AMES E. NELSON citizens of the United States, residing at luggertsville and Lancaster, respectively, in the county of Erie and State of New York, have invented a new and useful Improvement in Power- 'lransmitting Attachments for Motor-Vehicles, of which the following is a specifica- This invention relates to mechanisms adapted to be attached to motor vehicles for the purpose of transmlttmg power from the engine of a vehicle to the machinery or apparatus tohe driven.

The objects of the invention are to pro- 'vide a mechanism of this kind which can be easily and quickly attached to and removed. from a motor vehicle and which will necessitate only a slight change in the vehicle to adapt the same to receive the power transmitting attachment; also to n'ovide a mechanism of this kind which is so-ci'nistructed as to avoid the necessity of accurately alin- -ing the vehicle Wlth the machinery or appation. of a ower transn'iittiiw mechanism the engine.

Fig. 9 is a fi'agnicutalflv secti uil elevation showing the crank in n. sitiii 1 l0 start A power transmitting mechanism em the automobile, as shown, is supported on a: 6

frame member a to which the usual front. spring a is secured. a" represents a support secured on the frame member a which forms one of the points of suspension oi the motor, the front end 10* or the crank case or frame oi the motor bearing in the support of. a. Fig. 1, represents the front end of an. engine shaft on which is securcel the usual fan belt pulley 44 having a pin (1 extending throughthe pulley and shaft for seeming 7 the pulley to the shaft of. The pin (1 in ms as heretofore used cooperates with the usual crank (not shown) for starting the engine. will of these parts have heretofore been used in Ford ars and do not of themselves constitute a part of this invention.

ln order to adapt the car for attaching the power transmitting meclm;..sm thereto, the usual s'lzarti crank which coihseratesth the pin a? oi. the fan pulley is removed from the vehicle and the front end of the monk case is adapted to recei e a guide bushing; l5, being lor that purpose provided. in ihc construction showm with a screwthrcad which is adapted to receive a screwlhrcadrd portion of the guide bushing. A

comic-1m spindle (.3 extends through the lmshlir and provided at its rear end with arlutch or coupling; memher (1 having teeth (1 adapted to engage =with the pin a of the m pulley o, as shown in h rs. 1, and I 3. .u'i spring (:9, preferably arranged in the clutch member 0, bears against-the end oi the shaft a in such a i'nanner that the spring 1;" will norn'mllyhold the clutch member 0 out of engagement with the pin a of the fan pulley. flhe connecting spindle provided at its outer orfront end with asecond 1 clutch or coupling member 0' secured to the motor vehicle to adapt the some to be con-' nectcd with a power transmitting mechanism. Any other means may be employed for operatively connecting; t e connecting s spindle With the motor shaft.

The detachable part of the power transmitting mechanism includes a hearing or supporting member D which may be suitably secured in a fixed position relatively to the motor of the vehicle in suitable mannor, for example, by means of set screvv d engaging the outer portion of the guide bushing B. The bearing member-D has a bearing portion. d at theoutcr end thereof in which a bearing sleeve or ring of a driven. member E is rotatably held. The bearing sleeve is preferably made of brass or other metal having a good bearing surlace and may be secured to the driven mem bcr E in any suitable manner. In the construction shown 1' this purpose, the driven member E has a cup-shaped portion formed by an annular flange c" which surrounds the outer end of the bearing member D and to the inner face of which the besring ring 6 is rigidly-secured. The bearing ring 6 the driven member connected therewith are preferably held on the bearing portion of "o'f'the supporting or hearing member D by means of a ring or retaining flange F adapt ed to be secured to the supporting member l) by suitable means, such. as screws 7* which may be secured in place through. holes or.

' openingsf l ig. 6, formed in the driven member E. The driven member E is sortably connected With the spindle '8, being provided for this purpose, in the construction shown, with a central tubular estc sion or hub portion c having clutch teeth e adapted to en age with the, teeth of the clutch'meniber 0 when the driven member E is secured in its og'zerative ipllfilhlfl'fi by nicansof the ring-F, 1/ s being so proportioned that whee her E is held in its operative i the ring F, the connecting spir be pressed inwardly against the action the spring 0 to cause the clutch member 0 thereof to engage with the pin. a" of the fan pulley a,

Power may be transmitted by any snit-v able means, from. the driven member E to the machinery or apparatus to be driven. In the construction shown for this urpose,

' the driven member IE1 is provide on its cute face with projecting portions g forming part of a or: joint which, in the construction shows, includes an inter mediate member G: connected with pro so footing portions 9 bymeans of a pie. s and which in turn is connected by masses or" a pin 9 to a shaft or the like to be driven in order to facilitate the connecting of the.

engine with the apparatus or other device 'to be driven, the universal 301st oi" the Y Locales driven mernber is preferably connected with an erpansrble or telescopic shaft, including a tubular shaft member H connected by means of the pin 9 with the intermediate member G of the universal joint. The tubular shaft member H is provided with a key it slidably on aging in a keyway it formed in the shaft ll. Which is telescopically arranged in the tubular member H. The portion of thetubular shaft member in Which the key is securedis preferably strengthened by means of a reinforcing tube 92 A pin it extending into the key-way h of the shaft H limits the movement of the shaft lengthwise of the tubular member H.- The outer end of the shaft H is pref rably .connected to transmit power to a second universal joint I. By arranging the key it approximately midway between the ends of the tubular member H and by providing a stop pin h in the key-Way of the shaft H the extent to which the shaft H. can be drawn out of the tubular member H may be limited so that neither the key nor the key way is exposed. By means of the two universal joints and the telescopic shaft the necessity for" accurately alining the axis of the engine shaft With regard to the axis of the device to be driven is eliminated, so that other means may, however, be employed for transmitting power from the driven member E to the device to-be driven. In order to enable the engine to be started by means of a crank when the power transmitting mechanism is in place on the automobile, a clutch member I is preferably provided which, in the construction shown, is mount ed on the tubular shaft member H by any suitable means, such as a pin i. The clutch member l is provided With ratchet teeth adapted to be enga ed by means of a spanner Wrench or analogous device.

It is d irable to provide means for increasing the flow of air through the radiator when the power transmitting mocha nis'n is place on the vehicle, andthe fol? lowing construction isprefcrably employed for this purpose:

The supporting or bearing member D is provided at opposite sides with projecting portions is to which upright also supporting members or rods K may be secured, The npperends of the supporting rods are connected to a cross-piece is which may be suitably secured to thc'radiator cap 0; by any snitsbic means, each as a strap it, the cross piece 2'0 being preferably "adjustably .se-. cnrcd'to the upright rods K bymeaos set screws ll; represents a fan which is secured on a shaft 5 suitably journaled on a cross-bar Z secured on the upright fan supporting rods K, the ends oft-he crossbar Z supporting a frame or guard Z for t ll the fan. The fan may be driven by any suitable means, a belt Z being shown in the construction illustrated which passes over a pulley Z secured on the fan shaft Z and over the outer face of the driven member E. Any other means for producing increased circulation of air through the radiator may be provided.

In order to enable the engine to be cranked when the power transmitting device is not in place thereon, a crank is provided which is adapted to engage the teeth of the clutch member 0". The crank shown in the drawings for this purpose comprises the usual arm M having a handle an at one end and having, a hub portion m at the other end which is adapted to enter into the outer portion of the gulde bushing B and which is provided with ratchet teeth m The ratchet teeth m are held in engagement with the teeth of the clutch member 0* by means of a retaining bar or finger m adapted to on gage in an annular slot m formed. in the outer end of the connectingspindle C. 'lhc finger m is arranged ina hollow portion m of the crank arm M'and is pressed out- Wardly to engage in the annular slot m by means of a spring m arranged in the crank arm. The hub. portion m of the crank is yieldin ly pressed into the bushing B to. hold te ratchet teeth m in engagement with the teeth of the clutch meanber 0 by means of a spring we. engaging a pin m secured on the finger m in order to engage or disengage the crank from the connecting spindle C, the pin m is moved toward the outer end of the arm M to withdraW the finger m from engagement with the annular slot, and after the engine has been started, the clutch-member 0* can slip past the ratchetteeth of the crank by tore, ing the crank out against the action or the spring m The movement of theiinger m is limited by means of a slot an through which the'pin m extends and the pin m is moved against the action of the spring on by depressing the spring m to secure the crank on or remove the same from the con-' necting spindle C.

The apparatus described has the advantage that it can be very easily attached ,to the vehicle, namely, by securing the supporting or hearing member D on the-bushing B by means ofthe set screw (Z andfastening the strap on the radiator cap, and can be removed from the vehicle with equal. ease. The only difi'erence in. the appearance of the automobile is that the spindle C and the bushing B replace the usual crank or stud shaft of the vehicle. The automobile can be run by its own power into approximately the position which it is to occupy with re gard to the apparatus and any dilterence. in alinem'ent can.- be readily overcome by means of the universal joints and the telegig scopie shaft. The shaft drive is much superiorto a belt drive, which causes a side pull on the automobile and also requires very accurate positioningof the automobile with. regard to the apparatus to be driven.
